Initial furnace use setting off smoke detector

We have a new Catalina 333RETS and during initial use of furnace, the smoke detector went off. Is this simply some dust burning of or is there some other procedure we should take? I've read somewhere to run the A/C fan when using the furnace.

Runnerguy, That is normal. It takes a little while to burn off the dust plus the "New" of the metals in the heater. Open the doors and windows and let it run for a while.

I set my a/c fan on low when using heater. You did not,say if you have a fireplace. We do and I use that mostly and then set the gas heat to keep the temp from falling below a set temp. A/C fan on low..

As dalford said, it 's pretty normal for the first few uses. It'll stop after a while.

Running the A/C fan on low to circulate the air better is a good idea.

Dealer should have done this for you or informed you of it, during the PDI.

And every fall, or after not using the furnace for awhile, you will have a smell each time. Not a big deal but dust builds up and needs to be burned off, and does not last long. I try to run the furnace while stocking the camper for a trip, so I don't have to deal with it when I get to where I am going. I have never had the smoke alarm go off because of the furnace.

Funny Story

On the first morning of our first night out in our new 5th wheel, it was cold. I turned on the furnace to take off the chill. A couple of minutes in, the smoke detector began blaring! We jumped out of bed and out the door we went. The neighbors got a good show.
I poked my head in the trailer to see how high the flames were, only to smell that oily, dusty stink that a new furnace will give off. The smell gave it away and we returned to the trailer, took the battery out of the smoke detector and hid inside for awhile. The neighbors in nearby rigs never mentioned it, but I know they were whispering, "Newbies."

ayup... gotta "burn-off" the new furnace stuff. Paint and oil from production. I always figure a couple of hours on high heat will take care of it. Open all the windows and vents and have at it. Some dealers will take care of it during PDI if they can. I live in the Deep South and in the summer you can't get the furnace to fire. Fortunately A/C doesn't stink when you fire it up!
